My 1200GSA DOHC version broke down on the way back from the boil last Sunday.
Early thoughts were left hand coil pack, as it was only firing on the right pot.
Fortunately I have extended the BMW warranty so free recovery was sorted back to Bristol Motorrad.

Not coil pack so engine stripped on the left to discover that the timing chain had snapped.
They have never seen one do that before and I've not heard of one going.

So question is does anyone out there know of this happening before and more importantly what might have caused it?

Thankfully the warranty will cover it. Best 30 quid a month I've invested :S

New one & never heard it before, how badly is it mashed?

Best to ask on ukgser

Going down to dealers later to find out how much damage was caused.

I've searched on ukgser with no answers, I'll post up on there too.

Not familiar with this engine, but when you say firing on the RH pot, do you mean the right hand cylinder was running? Are these machines not just got 1 continuous chain which would mean a broken chain...no cylinders running? Will be interested to hear the outcome of this and you have avoided a massive bill.

Right pot is an old term for cylinder. Flat twin engine, each side has its own timing chain for its own camshafts and valves. Be lucky if they have escaped without damage.

How many miles has it covered.?
